Phased array radars — what next for GaAs?

AbstractMilitary phased-array radar systems (PARs) coming into service shortly will require thousands of radar modules. At this stage it is certain these will all be based on GaAs. They represent some conspicuously large orders for GaAs-based systems, but are in the main ignored by the general press. However, this GaAs success may be short-lived. For their next generation, radar companies are already looking to exploit the advantage of the more robust qualities of compounds such as SiC and GaN
